The fact that you are waiting to start doing your tasks doesn't mean that you don't really want to accomplish them, instead there are some fears or doubts that are feeding you with many reasons to procrastinate and wait.
Starting to take action is always the most difficult part of every task, but if you manage to start it and move forward, you will experience some positive feelings like feeling more powerful and successful that will act as big motivators to trigger you go on even more until you achieve your goals or until you accomplish your tasks completely.
Imagine yourself staying at home and doing nothing about the mess in your room. Most probably you will feel so lazy to clean everything there.
But if you tell yourself that you are going to clean 1/4 of your room and start to do it, after you have cleaned 1/4 of your room you will notice that you feel so motivated to continue your work until you clean it completely.
This happened because of the progress you did in cleaning your room. The same thing happens with everything you do. The progress you achieve through starting a certain task will make you persistent and you won't want to give up such progress you have done.
On the other hand waiting and procrastinating will do nothing more than increasing your fears and laziness to take action and will equip you with very attractive excuses to be busy with useless activities.
The power of momentum is very estimated from successful people and they dedicate their success to strong personality and to the power of momentum. You have to do nothing more than starting what you have to do, to experience such effects yourself whenever you want. It is certain that your fears and laziness won't hold you back anymore.
